Added a static folder and spawn a small HTTP server on runtests.
This is not really the best solution, as it uses pythons
simpleHTTPServer, but it works for now

As we have different executables for executing the runtests scripts,
runtests.sh is now renamed to runtests in order to stay consistent
over all testrunners

refs #4244
The dummy test only checks whether our build server has the correct
title when called. Also the i2w-config.js toolkit is provided
to help testing correct paths
